Application led September 27, 1915. Seri-a1 No. 52,784.

To all whom #may conoern'- v Be it known that I, HERMAN C. Pnox, a citizen lof the United States, residing at -Terre Haute, in the county of Vigo and State of Indiana,have invented a new and useful Roller-Bearing Car-Wheel, of which the fol'.- lowing is a specification.

It is the object of my invention to provide a roller bearing car wheel which shall have ber, which may surround ther-steel Y, invention.

lends of this stee longer life and shall require less frequent lubrication than those now in use. In carrying out m invention, I- cast in the hub of the car W eel a steel tube suffi.- cien'tly larger than the axle to receive the desired rollers, and provide this 'hub 4with integral' ia'ngeswhich project inward past the tube" and of the ,rolle `s. Preferably, Ik alsp provide a lubricant chame/ i l tubel refl ferred t0 and communicate therewith through suitable openings, and this chamber contains a ring which acts liliethey ordinary riiigioiler y to bring the lubricantto'thetop.` The/roll-I ers may be free in the roller chamber', or'xiiay be held therein b having on theirends pro=,'

in Itheends of t e roller chamber. vThe axle opening in the heel hub is preferably closedat the outer fa toinclosev the axle end, though if desired the `axle end may project' through. @,'y' c 'y The accompanying drawingillustrates my re 1 is a /verticfal' sectional view, through a car wheel equipped Kwith one form of my roller bearing," bowing mounting on the axle and car';Fig.f2 is a' similar vie\ v v showing a slightly different form,fwliich now prefer; and Fig. 3 is a section on the line 33 of Fig. 2.

The ear frame 10 has any suitable mount- Figu ing 11 on .the axle 12., this mounting conveniently consisting of a bearing surrounding ,v the axle and provided with cupshaped` `flange 13 which extends overthe end of the hub la of the car wheel 15. A hardened steel washer 16 is preferably interposed be- 'tweenfthe' end of thehub 14 and the be'ar ingdL Q-'Z The hub14= is cast around a steel tube 20', which is an integral tube and is-suiiic'iently larger linternally than the exterior Vof the axle 12 to provide a chamberfor an annular series of rollers 21 by which the wheel' 15 is carried nthe end of the axle 12. This roller chamber is completely inclosed,y for the hub 14 is `provided at its ends with iniwardly extending'iianges 22 and 22 which project radially inward past the ends of the l tube 20 and the rollers 21 at least `substantially to the surface of the axle 12; the liang 22 in Fig. 2 projects inward even farther and .forms a pomplete closure, for reasons hereinafter apparent. The' rollers 21 may be free in the roller chamber, so that they will',

not be restrained when the wheel is removed i 'from the axle, as shown in Fig. l; or they may be suitably retained in such chamber, y y

asby vhaving projections' 23 on their ends, which projections extend into annular ygrooves 24 on the inner axial faces of-the flanges A22 and 22, as shown in Fig. 2. In

the latter case, some special means must be provided for inserting theqrolleis 21 in the roller chainber,"as they cannot be put. in

serted, as can be donew in the arrangement shown in Fig. 1; and as a convenient means` for doing this, I have. provided a plug 25` through one ofthe inwardly pro]ecting farthest 'from the end ofthe axle'12.

chamber, so that when such plug is removed the rollers may be inserted or taken out.'

In order to lubricate the rollers 21, I pro-1 vide a special lubricant chamber, shown in Figs. 1 and 2. There is a lubricant chamber.

Preferably, there is cast in this chamber 21 a ring 32, which is of the proper sizelso that A it rests on the exterior of the tube 2() at the top' and just clearsl the bottoni of the lubricant chamber 30; This ring acts as an or-l dinary ring oiler to carry the lubricant to 'K if the top las the wheel 15 rotates. Lubricant is supplied to the lubricant chamber 3Q by a ico" passage 33, which assliown extends along the hub 111 parallel to the axis and is closed at its outer end by anplug 34. Lubricant'. 1

yneeds lto be supplied to theI chamber() only very infrequently, because by reasons of the flanges22 and 22 there is very little loss of lubricant from the roller ychamber, as the centrifugal force developed duringrotation A` y ably mounted in holes 4 0 in such cup-shaped Aao ` inner axial facesaiid said rollers having vtube to fit upon an axle, said hub having integral radially inwardly extending flanges Y b ltu.
